Chii chinonzi Carrier Aggregation?
Carrier Aggregation ndiyo yakakosha tekinoroji muLTE-A uye imwe yeakakosha matekinoroji e5G.Iyo inoreva tekinoroji yekuwedzera bandwidth nekubatanidza akawanda akazvimirira anotakura nzira kuti awedzere dhata uye huwandu.
Iwo chaiwo mapoka ndeaya anotevera:
Continuous carrier aggregation: akati wandei ari pedyo madiki anotakura akabatanidzwa mukutakura hombe.Kana vatakuri vaviri vane bhendi yefrequency yakafanana uye vari padhuze kune mumwe nemumwe nekuenderera mberi, inodaidzwa kuti inoenderera mutakuri aggregation mukati meiyo frequency band.
Non-inoenderera mutakuri aggregation: discrete akawanda anotakura akaunganidzwa uye anoshandiswa seyakafara frequency bhendi.Kana ma frequency mabhandi evatakuri maviri akafanana, asi spectrum haisi kuenderera uye pane gap pakati, inonzi discontinuous carrier aggregation mukati me frequency band;kana ma frequency mabhendi evatakuri maviri akasiyana, inonzi inter-band carrier aggregation.
Zvigadzirwa zveduChikamu cheFDM-6680shandisa carrier aggregation tekinoroji (CA), iyo inogona kuunganidza maviri 20MHz bandwidth vatakuri pamwechete kuti iwane 40 MHz isina waya inotakura bandwidth, zvinobudirira kuvandudza uplink uye downlink kutapurirana mitengo uye kuwedzera kusimba uye kuchinjika kwezvakatipoteredza kweyese isina waya yekutapurirana system.Iyo chaiyo performance ndeyekutevera:
1.Inogona kutsigira yakakura yakazara bandwidth, inotsigira 20MHz+20MHz mutakuri aggregation, uye peak data transmission rate inodarika 100Mbps.
2.Iyo inogona kutsigira kuenderera mberi kwekutakura kuunganidza uye kusingapfuuri kwekutakura kwekutakura, iyo inonyanya kushanduka.
3.Iyo inogona kutsigira mutakuri aggregation yezvikwata zvakasiyana-siyana uye kugadzirisa bandwidth yekutakura kuunganidza maererano nekukanganiswa kwezvakatipoteredza uye zviripo spectrum resources, zvichiita kuti zvive nyore kugadzirisa kune zvakasiyana-siyana.
4.Retransmission inogona kuitwa kune vatakuri vakasiyana-siyana kuti vadzivise kukanganiswa kwedata mushure mokunge mutakuri mumwe chete akanganiswa.
5.Inogona kutsigira frequency hopping yevatakuri vakasiyana uye kuwana kupindira-isina vatakuri zvinobudirira.
